SAID-IRON.

Application filed December 8, 1909.

To aZZ whom it may concern:

Be it known that I, MONROE SUNSHINE, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Sad-Irons, of which the following is a specification.

This invention relates to sad irons and particularly to those heated by a gas burner. Its objects are to improve the structure so as to get greater strength and durability as well as a more efficient operation, and at the same time to so simplify the construction that the parts may be made more cheaply and may be assembled more easily.

With these objects in view the invention consists in the novel features which will be apparent from the following description taken in connection with the accompanying drawings.

In the drawings,Figure 1 is a longitudinal section of a sad iron embodying my invention; Fig. 2 is a perspective View of the handle plate with one of the handle supports; Fig. 8 is a perspective view of a removable handle support; Fig. at is a perspective view of the burner; Fig. 5 is a perspective view of the deflecting plate; Fig. 6 is a longitudinal section of a sad iron embodying a modified form of my invention; Fig. 7 is a detail View of the deflect-.

ing ribs on the floor of the said iron; Fig. 8 is a sectional view of a modified form of gas and air mixer for the burner; Fig. 9 is a longitudinal section of another modified form of apparatus; Fig. 10 is a similar view of still another form; and Fig. 11 is a detail view showing the body made up of three parts.

As will be seen by reference to these drawings, the sad iron embodies a hollow body 1, preferably made of a single piece of metal, and having an opening 2 at one end to receive the burner, and small openings 3 at the top and at the other end to permit the escape of products of combustion and to draw the flame toward the said openings. The burner which heats the iron is embodied in a boss 4: of peculiar form. as shown most clearly in Fig. 4. This boss is provided with a central opening which receives the mixing tube 5, and there is a metal screen 6 at or near the end of this tube which may be made of perforated metal or wire gauze; held in said boss or in said tube in any suitable way, it being shown Specification of Letters Patent.

as held in place by a ring 7. This screen not only serves to more effectively mix the gas and air which are supplied through the tube 5, but also prevents the flame within the sad ironfrom flashing back to the point where the air and gas are mixed. The miX- ing tube 5 is secured in the boss in any suitable way. The boss 4 has the side wings 8 provided on their under surfaces with the lugs 9 which enter depressions 10 at the open end of the sad iron at the bottom near the sides. These lugs serve to lock the boss 4: against longitudinal movement, and it can be removed only by elevating it. Between these lugs there is a passageway for the admission of air below the burner to support combustion.

Centrally of the boss and on its upper side there is a flange 11 which is adapted to make contact with the upper edge of the sad iron body when the boss is in proper position. It will be observed furthermore that when the boss is in position the passageway through it, which constitutes the burner, is directed downwardly at an angle against the floor of the sad iron so that the flame from the burner will be spread out over the floor and will effectively heat that portion of the iron where heat is desired. In order to more effectively distribute the flame and heat I may make use of the ribs 12 on the floor of the sad iron radiating in such a way as to deflect part of the flame to the outer edges of the iron.

In connection with the burner I use in the sad iron a deflecting plate 13 which is preferably inclined downwardly from the open end where the burner is located, and in the forms shown in Figs. 1, 6 and 9 it is provided with feet 14 in order .to support its inner end from the floor of the sad iron, and may also be provided with the strengthening ribs 15. Centrally of its upper surface there is a rib 16 which is provided with a notch 17 having an inclined face for the purpose hereafter described. The outer end of the deflecting plate is provided on its under surface with the flanges or lugs 18 adapted to fit over and engage the flange 19 on the burner 1, the parts being so constructed that they will fit together and interlock against longitudinal separation.

The handle for holding the sad iron in the form shown in Fig. 1 is made up of the handle plate 20, handle supports 21, 22 and the handle proper 23. The handle 23 is preferably made of wood and it will be ob served that it has no hole or passageway bored through it to receive fastening means, but as distinguished from this is solid. It has a recess 24 at one end to receive the lug 25 on the handle support 21, and the recess or slot 26 at the other end to receive the lug 27 on the handle support 22, this last mentioned lug being substantially semi-circular in form to enter a corresponding recess or slot 26, so as to prevent the withrawal from or turning of the handle on the supports. It will be readily understood that by a simple transposition which would not affect the object to be attained, the lugs 25 and 27 might be upon the handle 23 and the recesses 24 and 26 might be in the handle supports 21,

22, if so desired, as indicated in Fig. 9.

It will be seen that the invention is not limited to any particular number, form or arrangement of lugs and recesses for securing stability of the handle when clamped in position, and that other means for securing the same result may be used without departing from my invention.

The handle plate 20 is provided on its under surface with the lugs 28 which bear in grooves 29 on the upper surface of the sad ironbody and is also provided with a finger 29" adapted to project through the opening 30in the top of the body. The lower end of the finger 29 is preferably inclined and engages the inclined face of the notch 17 in the deflecting plate 13, so that when the plate 20 is pressed down toward the body of the sad iron the deflecting plate 1.3 will be drawn forward into the body carrying with it the boss 4 constituting the burner, and thus firmly holding the burner in place. The action is in the nature of a clamping action and it secures the parts together in such a way that there is no looseness in the joints. The handle support 22 may have the horizontal extension 31 adapted to rest on top of thehandle plate 20 and it also has the downwardly projecting toe or lug 32 adapted to pass through the opening 33 in the handle plate, there being a groove 34 above the toe engaging the end portion 35 of the plate 20 adjacent the opening 33. This construction furnishes an interlocking pivotal connection between the support 22 and the plate 20, and in Order to release the support 22 it is necessary to move its upper end rearwardly. The inwardly projecting portion 31 has a slot or opening 36 near its inner end to receive a screw 37, which is adapted to pass through the opening 38 in the handle plate and to engage a screw-threaded opening in the top of the sad iron body. It will be seen that either or both handle supports could be made movable and that is not necessary to use the erg-tension 31 engaged by the screw to hold theli novable support in position, since the engagement of the toe or lug 32 with the top of the body or other part of the appara tus will ordinarily be sufficient, as illustrated in Fig. 9.

It willbe observed that in the construction shown in Fig. 1, when the screw 37 is tightened it will tend to turn the support 22 on its pivot in against the end of the handle 23, and thus the handle will be clamped between the supports 21 and 22. The handle 23 is of course placed in position, so that the lugs 25 and 27 will enter the recesses 24 and 26 in case such lugs and recesses are used before the screw is placed in position and tightened.

It will be observed that in addition to clamping the handle the tightening of the screw 37 will also not only lock the support 22 in position, but will also look the defleeting plate '13 and the connected burner, so that all of the parts will be held rigidly and without lost motion.

While I have shown in Fig. 1 one embodiment of my invention, it will be understood that its features are capable of various other embodiments and that I do not wish to be confined to the particular arrangement of the supports for the handle, the lug for interlocking with the deflector plate, or the particular connection with the burner. In Figs. 6 to 11 I have shown modified constructions and other modifications will occur to those skilled in the art.

In Fig. 6 I have shown the handle plate 38 having the handle support 39, and the lugs 40 fitting in grooves in the top of the sad iron body as in the construction shown in Fig. 1. This plate alsohas the finger 41 extending through an opening in the roof of the sad iron to interlock with the deflector plate. A second support 42 has a horizontal portion 43 adapted to fit on top of the plate 38 and on the under surface of this horizontal portion 43 there are inclined lugs 44 which enter slots 45 in the plate 38. The engagement of the inclined faces of these lugs with the edges of the slots draws the plate 43 forward toward the support 39, and thus the handle is clamped between the two supports and held by means of suitable interengaging projections and recesses as shown in Figs. 1 and 9. A screw 46 passes through a slot 47 in the arm 43 and through an opening in the plate 38 so as to engage with screw-threads in the top of the sad iron. In this instance, as in that shown in Fig. 1, the single fastening means which in the particular embodiment is shown as a screw holds all of the parts together in the act of assembling them. In other words, there is such interlocking action between the various parts which go to make up the apparatus that the single fastening will hold them all firmly together.

It will of course be apparent that instead of making the body of the sad iron in one piece the cover 52 may be made removable as shown in Fig. 9 and it is not necessary to have a separate handle plate, since one of the handle supports 53 may be secured directly to or made integral with the cover and the other support 5&- may have its lower hooked end pass through the opening 56 in the cover. Downward pressure on the cover 52 will make the lower surface of the hooked end bear on top of the boss l: so as to turn said support to clamp the handle and hold it in position. In this form I have shown the handle supports provided with recesses to receive the lugs or projections 57, 58 formed on the handle, and as before indicated these projections may be of any suitable number or form so as to retain the handle in position. The removable cover plate is provided on its under surface with a finger or projection 59 which engages the deflector plate 13 in the same manner as previously described, this plate being provided with downwardly projecting legs engaging the floor of the body. In this form I pass a bolt 60 through the removable top of the body, making engagement with the bottom of that body so as to clamp the parts together and I preferably make it as shown with screw threads on the upper end to receive the nut 61. The plate 13 is provided with an opening or slot 62 to allow the bolt to pass through it, and it will be seen that when the nut is tightened on this bolt all of the parts of the sad iron will be securely clamped together in proper position, and that all of the elements of the device may be taken apart by simply unscrewing the nut 61.

In Fig. 11 I have shown a similar construction except that the sides 63 are not made integral with the bottom but are made separately so that they will be clamped in position together with the other parts by the single clamping means, such as the screw 37.

In Fig. 10 I have shown a construction in which the deflector plate 13 is not supported from the bottom of the body, but has upwardly projecting lugs or feet 64: which engage the under surface of the top of the body, and in this form I use a bolt 65 which engages the deflector plate as shown, and passes upwardly through the top of the sad iron body. It will be understood that any suitable bolt or screw may be used. but I preferably make use of one having the nut 66 on the upper end where it will be accessible. In this form the deflector plate and theother parts of the apparatus are clamped together in substantially the same way as previously described, except that the deflector plate is drawn upwardly instead of being pressed down, and it will be understood that the finger on the handle plate making contact with the upper surface of the deflector plate tends to force its forward end down into close engagement with the burner 4, so as to clamp that burner in position.

It will be observed that in all of the forms shown a single fastening means clamps all of the removable parts together, and it will be readily seen by those skilled in the art how other arrangements may be produced utilizing this fundamental principle.

The gas which is supplied to the burner enters through pipe 4-7 and is discharged from a nozzle l8 into the coupling 49 which, with the pipe 5, constitutes the mixing chamber. This coupling has a single air inlet 50 adjacent the nozzle l8 and there is a wall .31 surrounding this opening or inlet of such shape that its outer surface can be easily covered by the finger of the person operating the iron. In other words, there is a short outwardly extending passageway or wall which has its outer edge made either in a straight plane so as to present a smooth surface for the finger of the operator, or some other suitably shaped surface which can be easily closed by the finger. The purpose of this construction is not only to prevent the interference with the mixing of the air and gas, by side drafts, but also to permit the operator to close the air inlet when lighting the burner, so that there will be no danger of the flame flashing back into the mixing chamber. In Fig. 8 the air inlet is shown at an angle to the nozzle as.

The pipe 5 may be held in the boss lby screw threads, as shown in Fig. 1; by a set screw, as shown in Fig. 9; or by any other suitable means. It will be observed that as shown in this form of the device the screen is held between the ledge within the boss -l and the end of the pipe 5, so that by simply removing that pipe the screen may be removed and either cleaned or a new one substituted for it. It is held in place simply '1 by assembling the parts as shown.

lVithout limiting myself to the details of the construction shown, what I claim is:

1. In a sad iron, the combination of a handle, supports for the ends of said handle,

cooperating with both supports for bring- T ing one of said supports toward the other to clamp the handle and for securing said supports together, and interlocking means independent of said first-mentioned means for connecting the handle and supports and consisting of projections on one partand corresponding recesses on the other part preventing removal of the handle when the supports are in place.

3. In a sad iron, the combination with a handle, of supports therefor at the ends, fastening means common to both of said supports engaging the body of the sad iron and so connected as to draw one of said supports toward the other to clamp said handle between the supports.

4. In a sad iron, the combination with a handle, of a fixed support for said handle at one end, a movable support therefor at the other end, and a single screw engaging said movable support and said iron, the parts being so constructed that upon tightening said screw one of said supports will be moved toward the other to clamp the handle and to secure said supports together.

5. In a sad iron, the combination with a handle, of two handle supports having overlapping horizontal sections, and fastening means engaging one of said supports and the body of the sad iron to hold the parts together, the parts being so related that tightening the fastening means will bring one of said supports toward the other to clamp the handle.

6. In a sad iron, the combination with a handle, of two handle supports having overlapping horizontal sections, and a single screw engaging one of said horizontal sections and the body of the sad iron to hold the parts together, the parts being so related that the action of the screw will clamp the handle between the supports.

7. In a sad iron, the combination with a handle, of a handle plate adapted to be secured to the body of the iron and having a support at one end and an opening at the other end, a movable handle support adapt ed to engage said opening, and means for fastening said parts together, the said parts being so constructed that the fastening means will draw the supports together to clamp the handle.

8. In a sad iron, the combination with a handle, of a handle nlate adapted to be secured to the body of the iron, said handle plate having an opening therein and an upright handle support, a movable handle support adapted to engage said opening, and means independent of the handle for fastening said parts together, the said parts being so constructed that the fastening means will draw one of the supports toward the other to clamp the handle.

In testimony whereof I aflix my signature in presence of two witnesses.
